Soft tissue perineurioma is a very rare tumor composed of entirely of neoplastic perineurial cells. A 54-year-old woman presented with a palpable mass in the right lower leg. The mass was excised. Grossly, the tumor measured 2.0x2.0x1.5 cm. The cut surface was well circumscribed, pale pinkish gray, and rubbery soft. Histological examination showed that the tumor was composed of spindle cells within collagenous and myxoid stroma. The tumor cells had elongated, tapering nuclei with long and thin cytoplasmic processes, and were arranged in fascicular, whorled, and storiform pattern. The tumor cells were positive for epithelial membrane antigen and collagen type IV and negative for S-100 protein. Ultrastructurally, tumor cells showed long and thin cytoplasmic processes, pinocytic vesicles, and incomplete external lamina. The diagnosis of soft tissue perineurioma was confirmed by immunohistochemical stain and ultrastructural study.

Background and purpose:The skeleton is the most common site of tumor metastasis in lung cancer.Skeletal complications from bone metastasis,such as severe bone pain,functional impairment,may substantially reduce quality of life,in some situations,may result in death.We explored the efficacy of ibandronate combined with chemotherapy in treatment of lung cancer with bone metastasis.Methods:Sixty-four lung cancer patients with bone metastasis were randomized into two groups:38 patients in study group received normal chemotherapy combined with ibandronate,and 26 patients in control group received normal chemotherapy only.Results:The response rate of pain relief in the study group and control group was 71.1% and 42.3%,respectively(P=0.006).In study group,serum alkaline phosphatise and serum calcium was decreased after treatment by ibandronate combined with chemotherapy(P0.05).Conclusion:Ibandronate is safe and well tolerated. Ibandronate combined with chemotherapy is effective in relief of the pain caused by bone metastases and may inhibit bone metastasis.

The old flexor tendon injury in the hand seen after 4 weeks from damage and associated with crushing injury, heavy scarring, fracture and infectious state has the difficulty to deliver the flexor tendon through fibro-osseous sheath and the pulleys. Treatment method depends on the circumstances of the injured flexor tendon and surgeons' judgement. We have treated twenty-three fingers of twenty-three cases, who had old flexor tendon injury, by advancement and tenolysis in 1 each, tendon graft in 5, and staged tendon graft in 16 from March 1989 through February 1994. The result was summarized as follows. 1. The old flexor tendon injury most commonly occurred in the fifth finger(11 cases, 47.8%)and in zone II (16 cases, 69.6%). 2. The most common cause was glass injury(15 cases, 69.6%). 3. 21 of 23 cases(2 thumbs excepted)were evaluated according to the original Strickland system. 14 cases of the staged tendon graft showed excellent(6 cases, 42.9%), good(5 cases, 35.7%)and fair(3 cases, 21.4%). 5 cases of the tendon graft showed excellent(2 cases, 40%), good(1 case, 20%), and fair(2 cases, 40%). 1 case of adhesiolysis and 1 case of advancement showed excellent and good results each. Little difference is observed in the method between the staged graft and tendon graft. 4. The degree of the associated soft tissue injury should be evaluated by the experienced hand surgeon before surgery and the delicate balance between protection and mobilization during the postoperative weeks is important as well as the surgical skill.

Keratosis punctata of the palmar creases (KPPC) is rare skin condition characterized by punctiform hyperkeratotic pits confined to the palmar and digital creases. Although this condition has been regarded as a variant of classical punctate keratoses, there are some differences between classical punctate keratosis and KPPC. We herein report a case of KPPC in a 22-year-old man who had numerous, tiny, hyperkeratotic pits limited to the palmar creases of both hands with typical histologic findings.

OBJECTIVETo compare the differences in the clinical efficacy on insomnia between shujing massage therapy and medication with estazolam.

METHODSEighty patients of insomnia were randomized into a shujing mass age therapy group (40 cases) and a medication group (40 cases). In the shujing massage therapy group, the spreading massage manipulation was applied along the running course of the gallbladder meridian of foot-shaoyang on the temporal area. The pressing and kneading manipulation was done at Yangbai (GB 14), Benshen (GB 13), Toulinqi (GB 15), Zhengying (GB 17), Chengling (GB 18), Shuaigu (GB 8), and Fengchi (GB 20), etc, 1 min at each acupoint. In the medication group, 1 mg estazolam was taken orally half an hour before sleep. The treatment was given once every day in the two groups. After the continuous treatment for 1 month, every dimensional score and the total score in the Pittsburgh sleep quality index scale (PSQI) and the clinical efficacy were evaluated between the two groups.

RESULTSAfter the intervention, the each item score of PSQI was improved as compared with that before treatment in the patients of the two groups (all P<0. 05). The differences in sleep time and the time for falling into sleep were not significant between the two groups (both P>0. 05). In the shujing massage therapy group, the scores of sleep quality, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score were all lower than those in the medication group (all P<0. 05). The total effective rate was 92. 1% (35/38) in the shujing massage group and was 84. 2% (32/38) in the medication group, indicating the significant difference (P<0. 05).

CONCLUSIONShujing massage therapy achieves the superior efficacy on insomnia compared with the oral administration of estazolam.

Objective To evaluate the efficacy of laparuseopic and open D_2 radical gastrectomy for gastric cancer. Methods From January 2008 to February 2009, 64 gastric cancer patients received laparoscopic radical gastrectomy (LAP group) and 60 gastric cancer patients received open gastrectomy (open group) at Changzhou No. 2 People's Hospital. Clinical parameters including operation time, blood loss, resection margin of gastric cancer, number of lymph nodes dissected, time for passage of flatus, time for out-of-bed activity, hospital stay and postoperative complications in the 2 groups were analyzed via t test and chi-square test. Results Gastrectomy was successfully performed on all patients. Mean operation time in LAP group was significantly longer than open group (t=5.56, P<0.05). There was no significant difference in the length of resection margin and number of lymph nodes dissected between the 2 groups (t=0.67, 0.86, 1.09, P>0.05). The mean blood loss, time for passage of flatus, time for out-of-bed activity and hospital stay in LAP group were significantly lesser than in open group (t=4.59, 5.56, 16.39, 4.79, P<0.05). Six patients in LAP group and 5 patients in open group had compli-cations postoperatively. All patients were followed up for 1-13 months, and no recurrence or death occurred. Conclusion Laparoscopic D_2 radical gastrectomy is safe and effective for gastric cancer.

OBJECTIVETo explore the effects of chronic hypoxia on left and right ventricular function and the expression of cardiac transient receptor potential canonical (TRPC) channels in rats.

METHODSForty eight SD male rats were randomly divided into control group (CON) and chronic hypoxic pulmonary hypertension model group (CH) (n = 24). In CH group, rats were exposed in chronic hypoxia environment (10% +/- 0.2% O2) to induce myocardial hypertrophy. After 3 weeks, mean systemic arterial pressure (mSAP), right ventricular systolic pressure (RVSP), left ventricular systolic pressure (LVSP), left or right ventricular pressure maximum rate of rise (LV/RV + dp/dt(max)), left or right ventricular pressure maximum rate of descent (LV/RV-dp/dt(max)), right ventricular hypertrophy index (RVMI) and left ventricular hypertrophy index (LVMI) were measured. Left and right ventricular myocardium tissue sections were stained by HE and observed under light microscope. Real-time polymerase chain reaction (real-time-PCR) and Western blot were performed to detect the expression of TRPC subfamily.

RESULTSRVSP, RVMI, RV + dp/dt(max) and RV-dp/dt(max) were markedly elevated in CH group (P < 0.01) in comparison to CON group. LVMI was markedly reduced in CH group in comparison to CON group (P < 0.01). LVSP, LV + dp/dt(max) and LV- dp/dt(max) had no significant changes in CH group in comparison to CON group. Right ventricular myocardial cells of CH group became thick, the nuclei stained deeply, the shape of nuclei became not regularity. Left ventricular myocardial fibers did not change significantly. There was significant difference in the levels of mRNA and protein of TRPC1 between CON and CH groups.

CONCLUSIONFor three weeks exposed to chronic hypoxia induced right ventricular hypertrophy specifically, raised the mRNA and protein expression of TRPC1 on right ventricular myocardial cells . TRPC1 might be involved in the development of cardiac hypertrophy.
